Thanks! I read about the strange PSU integration. Even if I have the case now, it would be ok is some folks could post good case ideas. With the 4090 generation, we all will likely need Full Tower cases if the cooling is supposed to be silent and efficient at the same time, especially if you don’t want water cooling. Don’t need the RGB gimmicks either. I build a RGB-fun-PC recently and use it for experiments. It looks cool like a Halloween Monster, but for serious simming requires a serious workstation. The bequiet Case should do it. The price was good too compared with the 2.0 Version, which I consider worse.

for a brand new pc, for the next 5 and more years, I would setup with 64gig RAM… It becomes more and more important, we see that in MSFS too ( usage of pagefile vs. none usage is a difference, and with my 64Gig I have only a fallback pagefile of 1gig ) . Spending now 2 x 32 GIG should give enough space for upgrade. The RAM timings are same with 2 or 4 banks.

I would fully agree to that. This is why I spec’ed the initial proposal with 64GB. When building a new one 2x32GB will be perfect and it leaves space for another 2x32GB or more if needed.

i would recommend number two with 32GB RAM

If (2), then 32 GB would make sense, while 64GB for (1) seems better in the great scheme-of-things of a top-of-line choice. Therefor good recommendation. Thanks.

Not a great scheme of things or a top-of-line choice.
It depends on what you are using it for.
For me, I usually fly with FS2020. I have 64 GB.
But I also have loaded many other apps that I use while flying.
Office 365
Chrome Browser - FS2020 Forum, WWT CJ4 Discord
Intel Insiders Communit y - Intel Arc (A770)
Music Apps
Video Recording
Weather
FS2020 is faster.
Every app takes RAM and switching among them is faster with less caching, etc…

I’d go with the 13900K and a 4080 16GB (which is the only vram option now fortunately).

Well given how the 4080 16GB appears to be priced, I’d just spend the extra and go for the 4090. 4090 seems a better “value” for what it is compared to what their comparable 30X0 series price/performance.

(11) The 12VHPWR cable is DANGEROUS! But NVIDIA doesn’t agree… - YouTube
You might want to watch this prior to spending all that money. I want new PC, however, this is one of the reasons I am waiting till next year, for these kinds of bugs to work themself out of the marketplace. Money talks and everything else walks. Hope Nvidia and Intel and the Power Supply folks get this sorted out. Provided for information and safety.
As aside, talked to my go to PC builder place and they are aware of this issue and are watching and waiting to see what changes. Ok, been years for basic electricity, but seems to me, that 10A (almost) needs at least #14-16 gauge wire to run without problems. I can tell based on size in pictures, none of those cables are at that size wire, the connectors is not sized correctly based on amp mentioned, and so, the whole thing to me is suspect, that is if card needs all 600W startup current it can grab. I sure am no expert here on it, so may be out to left field.
it doesnt supprize me… If we read the ATX 3.0 spec, which specified these 12VHPWR ( which exist, in my opinion, as only one reason: shifting bad gpu-power-circuit into the psu and let handle the psu the problems )
The connector performance requirements are as follows:
• Power Pin Current Rating: (Excluding sideband contacts) 9.2 A per pin/position with a limit of a 30 °C T-Rise above ambient temperature conditions at +12 VDC with all twelve contacts energized. The connector body must display a label or embossed H+ character to indicate support of 9.2 A/pin or greater. Refer for the approximate positioning of the marker on the 12VHPWR Right Angle (R/A) PCB Header.
( also funny that 30° , if we have in mind how hot some gpu’s go and so whats the temp nearby is )
Go for 64GB. Game can currently use >25GB in dense scenery areas even if it normally stays on the 10-15GB range, so 32GB will not be enough in a near future or when you intend to increase details. But be careful with the 4x16 sticks setups as this is only working well if your MoBo supports quad channel but not if it only supports dual channel. It´s better to take 2x32 sticks as most MoBos (including the newest ones) are dual channel ones. That way you can be sure to get the fastest RAM speeds without problems. The costs are basically the same and a future upgrade to 128GB is not really the case because this is not a server. With 64GB you have enough for the next 10 years 
Cheers

Thanks. Looks like using new ATX 3.0 PSU’s don’t show that issue:
“Most people don’t have those new breed ATX 3.0 PSUs, however, so Nvidia included a 12VHPWR to 4x 8-pin adapter in the box for use with traditional power supplies. But on a small number of units, those fancy new high-wattage rails and connections seem to be causing problems with the power connection”
I guess using a ATX 3.0 PS is the way to go for a new PC.
I probably would use 64GB in both scenario (1) and scenario (2). Since (2) is a DDR4 idea, the price for the 32GB->64GB upgrade RAM is reasonable right now.
I need to learn better what in MSFS causes RAM use vs VRAM use of the GPU.
as @geloxo mentioned, MSFS use already a lot… most users only check the memory usage in taskmanager, but thats not the whole truth. You must check the commited memory too ( resourcemanager, or activate the columns in taskmanager detail tab ) - we have some topics ( working vs commited memory ). And because of these there are users with 32GIG RAM where the pagefile is highly used. As former mentioned, I have a 1gig pagefile only and that mean, nowhere is the slow disc-drive involved, all happends in RAM in my case.
Whether the difference of ddr4 and ddr5 is it worth, I cant really say. But on the list for my next pc is DDR5 ( 2x32 )
